Retardation type buckling prevention anti-floating anchor and construction method thereof

Abstract

The invention provides a retardation type buckling prevention anti-floating anchor and a construction method thereof. The retardation type buckling prevention anti-floating anchor comprises an anchor body, a metal tube, retarding mortar and a cock body, wherein the metal tube is anchored in a foundation; the inside of the metal tube is hollow and is infused with the retarding mortar; the upper end of the metal tube is closed and the lower end of the metal tube is opened; the lower part of the anchor body is implanted into foundation soil; the upper part of the anchor body penetrates through the cock body and extends into the metal tube; the cock body is arranged at an opening in the lower end of the metal tube and is used for blocking the opening in the lower end of the metal tube and relatively fixing the metal tube and the anchor body; and a section of clearance is reserved between the upper end of the anchor body and the inner wall of the upper end of the metal tube. Compared with the prior art, the retardation type buckling prevention anti-floating anchor provided by the invention has the advantages that a better anti-floating confinement effect for a basement is realized, and the condition that the strength of the anchor body is reduced by repeated compressive tension is also avoided.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a slow-setting anti-buckling and anti-floating anchor rod and a construction method thereof. Background technique [0002] The anti-floating anchor rod is a commonly used structural component that provides anti-floating capabilities for underground buildings and underground structures. The rod body is made of steel bars, steel strands, steel pipes, etc., most of which are embedded in the foundation soil, and the upper end is anchored into the foundation. When the underground buildings and structures are subjected to upward water buoyancy, the anti-floating anchor rod will restrain the buildings and structures and prevent them from floating up. [0003] During the construction period, due to the use of precipitation means, the basement is not affected by the buoyancy of the upward water; with the gradual construction of the superstructure, the downward pressure gradually increase...

AI Technical Summary

Problems solved by technology

In this way, not only the anti-floating anchor rod has a poor effect on the anti-floating restraint of the basement, but also the strength of the anti-floating anchor rod body will decrease under repeated compression and pull.
